What are the reasons for the high fuel consumption of BYD F3?
2 Answers
BYD F3 high fuel consumption reasons are: Excessive engine carbon deposits: Excessive engine carbon deposits are mainly caused by using unsuitable fuel. Too much carbon deposit requires cleaning the engine carbon. In most cases, drive the car to a 4S shop, where professional technicians will clean the carbon deposits inside the engine. Oxygen sensor damage: Check the oxygen sensor. As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio of the engine. Once damaged, it will cause an imbalance in the engine's fuel-air ratio, and the fuel consumption will definitely increase suddenly. Failure to replace the three filters regularly: During the use of the vehicle, the oil filter, air filter, and fuel filter must be replaced regularly. If not replaced for a long time, the three filters will become dirty, causing incomplete fuel combustion and increased engine carbon deposits.
I've driven a BYD F3 for over a decade and found that high fuel consumption is quite common, mainly due to engine carbon deposits. Carbon buildup causes incomplete combustion and wastes gasoline, which requires regular throttle body cleaning to resolve. Additionally, a dirty air filter affects intake efficiency, increasing resistance and fuel consumption. I recommend checking and replacing it every 5,000 kilometers. Insufficient tire pressure is another issue, creating more resistance and consuming more fuel. Regularly inflating tires to the standard value can save a lot. Worn spark plugs cause poor ignition, leading to incomplete gasoline combustion, so it's essential to replace them with high-quality ones promptly. Oxygen sensor malfunctions are also common and can cause excessive fuel injection. I often use an OBD device to check it and replace it immediately if it fails. Developing a gentle driving habit and avoiding sudden acceleration can significantly save fuel. Running the air conditioner too aggressively in long-term congested areas also consumes more fuel. I usually turn it on at low fan speed only when it's hot.
